In this paper, a mathematical model to roll configuration of the rotary expansion of tubes is established, by using coordinate transformation.
根据斜轧扩径的工艺特点,利用坐标变换方法,建立了轧辊辊形的数学模型。
Due to difficulties of measurement,a reasonable physical measurement method was established,and the temperature distribution and thermal roll shape of work roll after rolling can be accurately measured.
热带钢连轧机工作辊下机后尚未完全冷却即进行磨削,残存的不均匀热变形导致磨削的工作辊辊形在空冷一段时间上机时很难达到工艺设定值。
Through the development of the secondary piercer unit with forward angle change type three roll structure, the role of “Rolling Effect” principle in three roll cross rolling is advanced, based on which the design principle of roll shape and pass is put out.
通过对变送进角型三辊铝管二次穿孔机组的研制，提出“辗轧效应”原理，在三辊斜轧中得到应用，并以此推出辊形与孔型设计原则。
The excellent roll profile can be obtained during stable casting,so the strip thickness along width is even.
同时,根据仿真结果设定初始辊形,并利用有限元方法对辊形进行优化,使结晶辊在稳定浇注时保持良好辊形,使铸带厚度横向分布均匀。
For 4-high plate rolling mill,the influence of slab wedge,temperature uniformity along width direction,rigidity difference,side-guide alignment,roll profile,APC(automatic position control) and AGC(automatic gauge control) on plate camber was analyzed.
基于4辊中厚板轧机,分析了坯料楔形、温度分布不均匀、轧机两侧刚度存在差异、推床对中不正、轧辊辊形和APC及AGC方式对中厚板侧弯的影响,得知温度分布不均匀、推床对中不正和轧辊辊形对侧弯影响较大,是今后控制侧弯的重要因素。
Analyzing the relation between the work roll profile and side camber of plate indicates that the side camber is liable to occur on workpiece with low stability during rolling if the work roll profile is convex.
分析工作辊辊形与侧弯的关系,可知工作辊有载辊形为正时,轧件易出现侧弯,轧制稳定性差·同时根据仿真计算得知:①支撑辊凸度保持不变,在同一轧件宽度下,如果工作辊无载辊形从凸形变成凹形,工作辊有载凸度逐渐减小;②支撑辊凸度保持不变,轧件越宽,则轧辊有载凸度的变化范围越大;③支撑辊凸度从正值变成负值,会使工作辊有载凸度曲线近似向上平移·为此采用以下措施有利于中厚板侧弯的控制:①在配辊时将上工作辊磨出一定的负凸度;②将支撑辊磨出一定的正凸度;③轧制初期多安排成品宽度较小的轧件进行轧制
